7.2.3 Network Address Translation (NAT)
NAT is an Internet standard that allows a network to use one set of IP addresses for
internal traffic and a different set of addresses for external traffic.
BlueGate 2100 handles address translations between the Local Area Network (external)
and the Bluetooth devices (internal) connected to BlueGate 2100.
The default is NAT enabled.
•
When NAT is enabled and :
DHCP is enabled, BlueGate 2100 receives its IP address from the DHCP
server, but internally assigns IP addresses to the devices in its private subnet
(the Bluetooth devices connected to it).
DHCP is disabled, BlueGate 2100 uses a fixed IP address (
Configuration >
Network Settings > Edit > IP Address
) on the external network but assigns
IP addresses to the devices in its private subnet (the Bluetooth devices
connected to it).
•
When NAT is disabled and :
DHCP is enabled, Bluetooth devices get their IP address from the
DHCP server.
DHCP is disabled, the IP address for each Bluetooth device must be
configured in BlueGate 2100’s NVRAM.
If both NAT and DHCP are disabled, a range of usable IP addresses must be configured
manually. If either NAT or DHCP is disabled and then the other is also disabled,
a window opens with fields to configure a range of usable IP addresses.
•
In the Range Starting From field enter the starting IP address.
•
In the No. of IP Addresses in this range field enter the number (< 255) of
addresses to assign and click the
Update
button.

Point will not be able to connect to BlueGate 2100.
